Growth Hormone Deficiency (GHD)

The OraGrowtH Phase 3 Trial is a multi-national trial. The goals of the trial are to study LUM-201 as a treatment for Pediatric Growth Hormone Deficiency (PGHD) in naive to treatment children and validate the LUM-201 predictive enrichment marker (LUM-201 PEM) strategy to select subjects likely to respond to therapy with daily oral LUM-201.

This study aims to evaluate the efficacy and safety of GB06 (a biosimilar of Norditropin®FlexProTM from Novo Nordisk) for the treatment of growth disorders caused by growth hormone deficiency (GHD) in children. It aims to determine whether the annual height velocity (an index of height growth rate) in children diagnosed with GHD after 52 weeks of GB06 intervention is comparable to that of Norditropin®FlexProTM. To achieve this, the participants will administer GB06 or Norditropin®FlexProTM at 0.035mg/kg/day for 52 consecutive weeks.

This study evaluates bone mineral density (BMD) in pediatric patients aged 5-18 years with conditions negatively affecting bone health, using REMS (Radiofrequency Echographic Multi Spectrometry), a non-invasive and radiation-free ultrasound technology. Bone health is crucial during childhood, when peak bone mass develops, and reduced BMD is associated with increased fracture risk. DXA is the current reference method but has limitations in children, including radiation exposure and growth-related measurement issues. REMS has been validated in adults and shows promise in pediatrics, despite the lack of reference values. The study is a single-center, national, non-profit interventional study lasting about 12 months. Participants will undergo REMS BMD measurement, clinical history collection, and assessment of anthropometric and pubertal parameters, with prior DXA data collected when available. The primary aim is to describe BMD values measured by REMS in pediatric osteoporosis, with secondary aims including subgroup analyses and comparison with DXA. A sample of 100 patients is planned. Statistical analyses will assess BMD distributions, correlations with clinical variables, and agreement between REMS and DXA using correlation coefficients and Bland-Altman analysis.

This study aims to evaluate the efficacy and safety of GB08 injection compared to Norditropin NordiFlex in pediatric patients with growth hormone deficiency (PGHD). It seeks to resolve the following questions: * 1: Does GB08 injection demonstrate comparable efficacy in treating PGHD at 24 weeks compared to Norditropin NordiFlex? * 2: Which dose (0.4 mg/kg, 0.8 mg/kg, and 1.2 mg/kg) of GB08 injection best balances efficacy and safety in treating PGHD at 24 weeks? * 3: Does GB08 injection maintain its efficacy in treating PGHD at 52 weeks compared to Norditropin NordiFlex? To achieve these, GB08 injection will be compared to Norditropin NordiFlex to see if it provides a more effective or safer treatment option for PGHD. This is a Phase II/III, Seamless, Multicenter, Randomized, Open-Label, Positive-Comparator Controlled Clinical Trial with two stages. Stage 1 answers questions #1 and #2 by comparing the efficacy and safety of GB08 injection and Norditropin NordiFlex intervention among PGHD at 24 weeks. It involves four groups (n=16 each): GB08 0.4 mg/kg, GB08 0.8 mg/kg, GB08 1.2 mg/kg, and Norditropin NordiFlex 0.035 mg/kg. GB08 and Norditropin NordiFlex will be administered once weekly and once daily, respectively. The primary outcome measurement is annualized height velocity (AHV) at 24 weeks. Other measurements include growth hormone levels, safety parameters, immunogenicity markers, and pharmacokinetic/pharmacodynamic profiles. The optimal GB08 dose will be further investigated in Stage 2, which answers question #3. At this stage, PGHD patients will randomly receive either GB08 injection or Norditropin NordiFlex intervention for 52 weeks (n=102 for each). After that, the efficacy and safety of GB08 will also be detected.

This is a Multi-national Trial. The Goal of the Trial is to Offer Subjects Who Complete 12 Months in the LUM-201-10 Phase 3 Trial up to an Additional 36 Months of Treatment of LUM-201 While Evaluating Safety and Tolerability of LUM-201.
